The grey cast iron cylinders from TNT are a very good alternative to the usually very expensive original cylinders. They do not provide any performance increase and can therefore be used legally on public roads. Of course, you can also drive significantly faster than 25 / 45 km / h with this cylinder, since other components such as the exhaust system, carburetor or CVT are adjusted. Included in the scope of delivery: Cylinder Piston incl. 2 piston rings and 2 piston clips and a set of piston pin seals Cylinder head is not included. The original can still be used. As an alternative, we offer inexpensive cylinders from Maxtuned, Motoforce or TNT. Data sheets and notes: Cylinder replacement.pdf
